Popis

PD IEC 61956:2001


This standard PD IEC 61956:2001 Methods of test for the evaluaion of water treeing in insulating materials is classified in these ICS categories:
  • 29.035.20 Plastics and rubber insulating materials
Prescribes methods of test for the evaluation of water treeing in polyethylene (PE) and crosslinked polyethylene (XLPE) compounds, as a means to assess their relative performance under alternating (a.c.) electric stress, in the presence of water. Two methods are described, method I covering the evaluation of insulating materials alone, and method II covering the evaluation of insulating sandwiches consisting of an insulating material in intimate contact with semiconducting screens.
